Appcelerator has conducted a study about developer interest in mobile platforms including iPad, iPhone and Android. The survey was to determine general interest in the different platforms.

The results are rather interesting as it seems that interest in iPad development has actually declined from January to March. In January, 90% of developers expressed interest in creating an iPad app of some sort within a year. Now, that number is around 80%. General developer interest in the iPad is currently at 53% while January was at 58%. Why the decline? I’m not sure.

In contrast to the iPad, Android edges it out overwhelmingly at 81% in overall general interest. This is up massively since January where interest was only at 68%. Why the increase? Well, The Nexus One and support from just about every major phone manufacturer has certainly helped along with huge sales of the Motorola Droid.

Now, earning that 81% for Android puts it in direct competition with the iPhone for developer interest. Still, most app makers are developing for the iPhone first and porting to Android later.
